The phenomenon of girls with low self-esteem who jump into bed with men (or women) they barely know, then afterwards are so filled by regret and disappointment and loneliness that they in some way try to justify their behavior by claiming that they were taken advantage of and didn't make a conscious personal choice.
"Well why did you sleep with him/her if it makes you this upset? Didn't you want to?"
"I...I don't know if I wanted to...I feel like I was taken advantage of."
"That's buyer's remorse bitch."
